Abstract

The invention provides a high-whiteness bone china for daily use, and a preparation method thereof. The high-whiteness bone china for daily use is prepared from the following components in percentage content: 21 to 24 percent of kaolin, 7 to 11 percent of feldspar, 10 to 15 percent of quartz, 1.3 to 2.6 percent of sepiolite fiber, 0.3 to 1.2 percent of brucite, 2 to 5 percent of diatomite, 0.48 to 0.65 percent of sodium alginate, 0.15 to 0.25 percent of a dispersing agent and the balance of bone ash powder, through the steps of mixing, heating, precalcining, crushing, ball-milling, sintering and the like. The high-whiteness bone china for daily use has high thermoplasticity, high heat stability and high processability; and the prepared product has flat and smooth appearance, the mechanical strength and the light-transmitting property are remarkably improved, the whiteness can reach 82 percent, the rate of finished products can reach above 95 percent, and the comprehensive quality of the china for daily use is effectively improved.

Description

technical field [0001] The invention relates to the technical field of daily-use ceramics, in particular to a high-whiteness daily-use bone china and a preparation method thereof. Background technique [0002] The ceramic industry is a high-energy-consuming industry. With the rapid development of the ceramic industry, the problem of serious energy consumption has become increasingly prominent. According to statistics, in the ceramic industry, my country's energy consumption is 3.1 times the world average, 4.3 times that of OECD (Organization for Economic Cooperation and Development) countries and regions, and 9 times that of Japan. In the process of ceramic production, a large amount of raw materials such as kaolin are consumed every year, and the situation of depletion of kaolin and other resources is very serious. With the country's attention to environmental protection and the emphasis on the rational use of resources, the structural adjustment of the ceramic industry ha...
